METAL FILING.

Specification of Letters Patent.

Patented May 8, 1906.

1'0 1.1M whom, it may concern.-

Be it known that I, JAMES J. HAROLD, a citizen of the United States ofAmerica, residing at Jersey City, in the county of Hudson and State ofNew Jersey, have invented certain new and useful Improvements in MetalPiling, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to im rovements in metallic piling as used 'in suway, foundation, and irrigation work, clams, mine-shafts, caissons, seawalls, locks, coffer dams, retaining-walls, and similar structures, andcomprises flanged beams, preferably of the channel-beam type, providedwith interlocking members.

Referring to the accompanying drawings, Figure 1 is an end view of a runof my piling, showing the members interlocking on both sides; and Fig. 2is an end view of a run of my piling, showing the members interlockingon one side. Fig. 3 is a perspective view of Fig. 1, and Fig. 4 is aperspective view of Fig. 2. Fig. 5 is a side view of Fig. 3, and Fig. 6.is a vertical sectional view of a single beam and two interlockingmembers. Fig. 7 is a perspective view of one of the plates which may beattached to the reinforcing-block of the interlocking member, and Fig. 8is a vertical sectionaiyiew showing a plate inclined at both ends. I

A and B are the beam members, arranged so that the flanges of eachmember engage the flanges of interlocking members and are retained inplace by the plates attached to the blocks of wood. or other suitablematerial attached to channel-beams and comprising the interlockingmembers. .In Figs. 1, 3, and 5 these plates are indicated as O and D onthe front and back of the piling, respectively.- Each plate may befastened by bolts which pass through the plate, the block or beam, andthe channel-beam. One side of the plate is projected to engage the backof the adjoining beam and retain same in position. In Figs. '2 and 4these plates are indicated as D, and both sides of the plate are.projected for engaging the backs of the adjoining beams. The lower plate(shown in Fig. 6) also shows the lower end turned up, thereby preventingthe separation of the plate from the beam by sharp stones or otherobstructions encountered in driving.

Where a plate tapered at both ends is employed such as is indicated atE, Fig. 8thc piles may be withdrawn more easily, as the top of theinterlocking member will not present the same resistance in thewithdrawal of the pile.

Modifications may be made in the construction and arrangement of partswithout departing from the spirit of my invention.

Having described my invention, what I claim, and desire to secure byLetters Patent, is

1. In piling, flanged beam members and interlocking members, saidinterlocking members tapered toward the bottom of the piling andprovided with projecting flanges ada ted to retain saidflanged beammembers in p ace.

2. In piling, flanged beam members and interlocking members, saidinterlocking members tapered from the center toward the top and bottomof the piling and provided with flanges adapted to retain said flangedbeam members in place.

3. In piling, flanged beam members and reinforced tapered interlockingmembers,

said interlocking members provided with pro-- j ecting flanges adaptedto retain said flanged beam members in place.

In testimony whereof I alliX my signature in presence of two witnesses.
